Simulation of the nonlinear mechanical response of materials with explicit representation of microstructural features is extremely challenging. These models typically involve a very large number of degrees of freedom, and are prone to convergence difficulties when searching for roots to nonlinear equilibrium equations. We focus on an idealized material… (More)

The mechanical behavior of thin elastic _lms deposited onto structural alloys plays a critical role in determining _lm durability[ This paper presents analysis of an impression experiment designed to evaluate some of the relevant properties of these _lms[ The modeling provides quantitative strain information which can be used to estimate the fracture… (More)
